Abstract:
The class of Ubiquitous Information Systems (UIS) has recently gained
attention but is governed by ad-hoc methods, e.g. “wild-west” prototyping.
UIS require design approaches that keep a holistic view of situations in
which single users and groups interact with one another and with accessible
services. A conceptual modeling approach for Ubiquitous Information Systems
(UIS) is presented as a central part of a UIS design methodology. Three
conceptual models are used for step-wise derivation of machine-executable
design models for distributed service infrastructures: narratives,
pattern-based diagrammatic conceptual models (Pre-Artifacts), and formalized
propositional conceptual models.
